Tri writes: The Open Source Industry of Australia (OSIA) has formally contacted Standards Australia, requesting that Microsoft's Office Open XML (OOXML) format not be endorsed by the body as an ISO standard.

"Quite apart from the technical problems with OOXML, the main problem from OSIA's point of view is a substantive one — the 'standard' is designed so that it can only be implemented by a single vendor", said Brendan Scott, Director of Open Source Industry Australia. "So, while in theory a third party could create an independent implementation, in practice it is very unlikely", he said.
